The original EPIC ONE air rifles have become a worldwide hit thanks to their top-class performance, premium materials, and futuristic design. The Epic designers now come with something a bit more classic – the ONE Walnut series with an elegantly shaped walnut stock.
Introducing EPIC ONE – the new icon from the world-famous company EPIC AIRGUNS based in the Czech Republic. The EPIC team has capitalised on all the experience gained from producing the successful TWO model and transformed it into its compact bullpup successor. High manufacturing quality is evident from every angle – for example, the main monoblock of the air rifle is made from a single piece of metal on a 5-axis CNC machine.

PCP SYSTEM
This bullpup boasts a new adjustable HIGH-POWER balanced valve, which guarantees maximum power with minimal hammer spring tension, making it easier to cock the side lever. At the same time, it reduces air waste and thus increases the shot count per fill. The hammer pre-tension can be adjusted externally using a screw located above the buttpad.
The air cylinder with a maximum working pressure of up to 300 bar (4350 PSI) can be filled using the supplied filling pin with a standard 1/8" diameter compatible with a standard quick coupler. The air rifle is equipped with 2 manometers – one indicating the current pressure in the cylinder, the other for the pressure in the externally adjustable regulator, which can be set using the included key within a range from 50 to 190 bar (always follow the instructions in the manual).
To achieve an even more consistent muzzle velocity, the regulator is complemented by a large power plenum (63cc on the version with 420mm barrel and 95cc on the 550mm and 700mm barrels).
BARREL
EPIC ONE air rifles are fitted with a non-choked CZUB barrel (Česká zbrojovka Uherský Brod) with 12 grooves and 1:17.7” twist rate. The muzzle end is equipped with a 1/2UNF thread for mounting a sound moderator. The carbon shroud serves to stiffen the barrel and at the same time allows barrel pre-tensioning (harmonic tuning).
Air rifles with 420mm and 550mm barrel length are additionally equipped with an integrated K-Baffle type sound moderator, also ending in a 1/2UNF thread.
On the version with a 700mm barrel, after unscrewing the segment with 1/2UNF thread and revealing the M27x1 thread, it is compatible with the EPIC AIRGUNS sound moderator or with a muzzle brake.

Barrel kit
Thanks to the barrel kit you can freely change the barrel length and the overall calibre of the air rifle. The set includes everything you need (barrel, carbon shroud with M27x1 thread, adapter for 1/2UNF moderator, 1/2UNF thread protector, transfer port, and loading probe).
To achieve the very best results with heavy pellets and slugs, a barrel kit with a non-choked polygonal Lothar Walther barrel (6 grooves with 1:17.7” twist rate) is also available.
MAGNETIC MAGAZINE
The ONE series is equipped with a new pre-tensioned magazine with a magnetically closed cover. To load it, simply rotate the inner part and insert the first round, which locks the rotary mechanism. Thanks to its compact dimensions, the magazine does not disrupt the overall appearance of the air rifle and does not interfere with handling. In addition, it holds projectiles up to 14mm long.
BULLPUP DESIGN
Thanks to the smart bullpup design, the ONE model has exceptionally compact dimensions while the air rifle remains perfectly balanced. For proper cheek weld there is a rubberised cheek piece that can be freely moved along the 11mm dovetail running along the entire main block of the air rifle. The raised Picatinny rail with up to 30 MOA incline is also adjustable, making it easier to zero the scope for shooting at extreme distances.

Walnut stock
The Walnut series, instead of an adjustable aluminium buttpad, boasts a wallet stock made of walnut wood, manufactured by the renowned Czech company KLINSKY, who have refined it down to the smallest detail. The selected wood has a unique grain pattern, making each air rifle truly one of a kind. If you already own the standard EPIC ONE version, you can purchase the wooden stock separately here.
You can also purchase the Top Rail EPIC ONE – a tuning Picatinny rail with a number of M-LOK slots on the sides or an Arca-Swiss mounting platform for versions with a 580cc and 300cc carbon bottle.

For mounting additional accessories, you can use two short Anschütz UIT rails on the sides of the barrel.
Trigger mechanism has been fine-tuned down to the last detail. Using several screws you can adjust the trigger pull weight, the travel of the first and second stage, and the height and rotation of the trigger blade. The reliable lever safety is located directly in front of the trigger, so you do not have to take your eyes off the target when disengaging it. The easily reversible side lever with an extremely smooth action is already a standard feature on EPIC air rifles.
VARIANTS / CONFIGURATIONS
EPIC ONE Walnut is available in three construction variants:
- Classic – standard aluminium cylinder and short lower Picatinny rail
- CFB (Carbon Fiber Bottle) – carbon bottle and short lower Picatinny rail
- CFB Arca-Swiss – version with carbon bottle complemented by an Arca-Swiss mounting platform with a number of M-LOK slots on the sides and a lower Anschütz UIT rail

NOTE – The EPIC ONE air rifle offers many options for adjusting internal and external components, and some modifications require extensive knowledge of PCP air rifles. Always follow the user manual – incorrect procedure may result in irreversible damage to the air rifle and loss of warranty.
